The XAR project aims to provide an easily extensible archive format. Important design decisions include an easily extensible XML table of contents for random access to archived files, storing the toc at the beginning of the archive to allow for efficient handling of streamed archives, the ability to handle files of arbitrarily large sizes, the ability to choose independent encodings for individual files in the archive, the ability to store checksums for individual files in both compressed and uncompressed form, and the ability to query the table of content's rich meta-data.

  2. Open APK File APK files are used by Google Android operating system to store installation packages for applications. APK package stores compiled Android application. It also contains all resources which are required for Android application to run.

The XAR file format has three main regions, The Header, The Table of Contents, and The Heap. The header is a small binary data structure that identifies the file format (file magic). The table of contents is parsed as an XML document. The heap occupies the remainder of the file. Files' data are stored in the heap.

Files in xar are individually compressed. This allows for quick extraction of individual files without the extra disk space requirements and CPU usage of extracting the entire archive, as compared to a compressed tar archive. This makes xar useful for quick restores of accidentally deleted or overwritten files, from a backup archive. Additionally, this means xar can use different compression methods for each file in the archive. For instance, it might not be a good idea to try to try to compress an already compressed file, but a large file might benefit greatly from using bzip2, whereas a small text file would be better served to use gzip.

What is a NUPKG file?

A NUPKG file is a code package used by NuGet, a Microsoft Visual Studio component that allows developers to create and share packages for use in .NET projects. It contains packaged source code, as well as instructions for how to use that code. NUPKG files are built from .NUSPEC files, which are themselves built from .DLL assemblies.

Prior to 2012, developers had to manually install NuGet as an extension to Microsoft Visual Studio. But over time, NuGet and the NUPKG format proved so essential that Microsoft began installing NuGet Package Manager with Visual Studio by default. These days, developers share thousands of NUPKG files using NuGet.org and NuGet Package Manager. Popular NuGet packages include Microsoft Entity Framework, jQuery, and JSON libraries.

How do I open a NUPKG file?

Generally, developers do not open NUPKG files. Instead, they import the files into Microsoft Visual Studio, so they can include the code contained within NUPKG files in their development projects.

To import a NUPKG file into Microsoft Visual Studio:

  1. From the Visual Studio toolbar, select Project → Manage NuGet Packages. The NuGet Package Manager appears.
  2. Select the gear icon that appears in the upper right-hand corner of the NuGet Package Manager. The Options window appears, showing a list of NuGet package sources.
  3. If the folder containing your NUPKG file does not appear in the Package sources: field, add that folder as a package source (by selecting the button and then entering the path to your folder in the Source: field). Then, select .
  4. From the Package source: dropdown menu, select your new package source.
  5. When your NUPKG file appears in the NuGet Package Manager, click it and then select .

Because NUPKG files are compressed with zip compression, you can also extract the files contained within them using zip utilities such as:

  • Microsoft File Explorer (Windows)
  • 7-Zip (Windows)
  • Apple Archive Utility (Mac)
  • Corel WinZip (Windows and Mac)

After you extract the files contained within a NUPKG package, you can open and view them normally.

NOTE: If you have trouble extracting the files contained within a NUPKG file, you can try renaming the file to use the .ZIP extension before decompressing it.
